For three years, First Quantum's whole investment case came down to one hole in the ground. Cobre Panamá — the company's biggest copper mine, about 1.5% of the world's copper supply and roughly 40% of FQM's revenue — was ordered shut in November 2023 after Panama's Supreme Court declared its mining concession unconstitutional. The mine stopped. FQM sued the country for about $20 billion. The "old story" investors priced was a dead flagship, heavy debt, and a lawsuit that might never pay.
That story has quietly stopped being true.
In the second quarter of 2026, First Quantum processed its first batch of stockpiled ore at Cobre Panamá since the 2023 closure — 3,216 tonnes of copper concentrate, pulled from 2.1 million tonnes of ore the Panamanian government had authorized it to work. It was a small number. But it was the first time in three years the mine produced anything, and it sits on top of a chain of events that has reset the entire file.
The file was reset, not closed
The sequence is the point. In March 2025, First Quantum dropped the $20 billion arbitration — the single clearest signal that it wants the mine back, not a courtroom award. In June 2026, an independent audit by SGS, commissioned by Panama's own environment ministry, found the site "broadly compliant" with its environmental, legal and fiscal obligations — an 87.7% score, with 361 of 370 commitments met. And on April 7, Panama authorized the processing program that produced that first concentrate.
Now the government is weighing how to hand the mine back. Reporting in July described a public-private structure in which a state-owned entity would take 35–40% and FQM would keep 60–65% and stay as operator; a simple lease is the fallback. Panama's trade minister has said the decision will come by the end of the year.
The market has spent three years pricing a permanently dead mine. It is now being asked to update to a mine with a compliance rating, a working stockpile program, and a live decision date.
The cash flow that was hiding
Here's why the reset matters — and it's not about the headline.
Even with Cobre Panamá shut, FQM generated $2.1 billion of operating cash flow and $1.7 billion of EBITDA in 2025. That number is the rest of the fleet — anchored by Kansanshi and Sentinel in Zambia — doing the work. The shutdown cost the company its biggest engine; it did not stop the others.
Now two things have happened at once. First, the copper price is near records — Comex copper has traded around $6.70–$6.85 a pound in late August and early September. Second, First Quantum has finished hedging. Every derivative contract was completed by June 30, which means the company is now fully long copper into a price it has never had.
You can see the turn in the quarter. First Quantum swung from a $196 million net loss in the first quarter of 2026 to $136 million of net earnings in the second. Q2 EBITDA was $400 million — dragged down by $164 million of realized losses from the now-finished hedge program and a $51 million hit from keeping Cobre Panamá safe. Strip out the one-time hedge damage and the underlying business is running materially better than the print suggests.
Production guidance was raised, not cut: 2026 copper output is now 405,000–475,000 tonnes, up from 375,000–435,000 a quarter earlier, at a C1 cash cost of just $2.15–$2.40 a pound. Against a $6.70+ metal, that is a wide margin.
Be straight about what I'm giving you: First Quantum does not publish a clean free-cash-flow figure, so this bridge runs on EBITDA and operating cash flow as the anchor, and that carries more uncertainty than a guided FCF line would. On a market cap of roughly $27 billion in US terms and about $5.4 billion of net debt, the company trades in the mid-teens on clean 2026 EBITDA of about $2 billion. That is not screaming-cheap. But it is a lot below 10 if Panama says yes and the mine adds back a fifth or more of its copper output at below-average cost. The gap between those two multiples is the whole investment.
You don't need a DCF for this — DCFs are the illusion of control when the real variable is a government decision. The case is one binary plus one input: does Panama say yes, and how long does copper stay near record.
What would break it
The bear case is real, and I'd rather name it than smooth it over.
This is a political binary, not an operating number. The 2023 shutdown was born of street protests, and Panamanian officials still fear a restart would reignite them. The decision could slip past the end of the year, or come back on terms that hand the state a bigger stake and a heavier royalty and tax bill — which would shave the very margin this case depends on.
Copper is the other swing factor, and it has been whipsawing on US tariff uncertainty. A pullback from the highs would hit FQM's cash flow directly now that it is unhedged.
Costs are the third. Fuel and the weakening Zambian kwacha are adding roughly $0.25 a pound to C1, and the ZESCO power force majeure is unresolved. The company carries about $5.4 billion of net debt and roughly $550–575 million of annual interest, so it cannot afford a long stall.
The break condition is specific: if the Panama decision slips well past 2026 or comes back on materially worse fiscal terms, and copper rolls off its highs at the same time, the operating case — not just the sentiment — breaks. That is when the cheap multiple stops being a discount and starts looking like it earned the pain.
Where this lands
I can be wrong, and I'd rather be early and wrong than late and quiet about it. But the setup has a shape to it. The market is still pricing the old risk profile — a dead mine, a $20 billion lawsuit, a debt problem — while the operating setup is already getting cleaner: a compliance audit passed, the first concentrate out of the ground in three years, the lawsuit dropped, production raised, the hedges off, and a decision date inside the next year.
This is not about excitement. It's about a business that may soon look a lot harder to dismiss once the free cash flow shows up and the flagship mine — the one thing that broke the story — is actually in the running again.
